Port NavBar color picker 2/2
Port: Set navbar background and statusbar background back to a drawable by default (2/2)

but add in options for color alpha, default bg plus color/alpha, or default bg only. Choosen by user.
This will make themes that theme navbar/statusbar background work correctly if set to default of course. Plus maintain the choice of user selectable color/alpha.
